Square Hinge with Countersunk Holes

For wholesale cabinet hinge orders, Yitai Lock carries the Square Hinge with Countersunk Holes in both CL235-1 and CL235-2, so you can cover different door sizes without switching suppliers. The CL235-1 is the larger of the two at 64 × 79 mm, while the CL235-2 at 54 × 64 mm works well on lighter or smaller doors. Screws aren't included but can be ordered separately — usually in packs of 1,000, with smaller quantities available if you reach out directly.

Model Options and Dimensions

The Square Hinge with Countersunk Holes is offered in two base models. The CL235-1 measures 64 × 79 mm, with a leaf thickness of 5 mm in zinc alloy and 5.6 mm in 304 stainless steel. The CL235-2 is the smaller of the two at 54 × 64 mm, with a zinc alloy thickness of 4.8 mm and a stainless steel thickness of 5.5 mm.

Each model is available in multiple material and finish combinations. The Square Hinge with Countersunk Holes CL235-1 and CL235-2 both come in black zinc alloy and bright white zinc alloy. The CL235-1 and CL235-2 are additionally available in brushed stainless steel, giving a total of six variants across the two models. This range allows specifiers to match the hinge finish to the cabinet surface or to the operating environment.

Countersunk Hole Specifications

The countersunk holes on the Square Hinge with Countersunk Holes are sized to match each model and material. On the CL235-1, the countersink diameter is Φ8.5 mm for zinc alloy versions and Φ9.5 mm for stainless steel versions. On the CL235-2, the countersink diameter is Φ6.8 mm across both material types.

Screw selection should account for the door panel thickness, the hinge leaf thickness, and the depth of the countersink. The Square Hinge with Countersunk Holes is designed so that correctly selected screws sit flush or just below the leaf surface. Screws are not included with the hinge but can be purchased separately; standard packs are 1,000 pieces or more, and smaller quantities are available on inquiry.

Material and Surface Finish

The Square Hinge with Countersunk Holes is manufactured by die casting, which gives each leaf precise dimensional consistency across production batches. Zinc alloy versions are finished in either gloss black or bright white — both are durable coating options suited to indoor cabinet environments. The stainless steel versions use 304 grade material with a brushed finish, which provides corrosion resistance suited to enclosures in humid or mildly corrosive surroundings.

It is worth noting that the stainless steel variant of the Square Hinge with Countersunk Holes carries a slightly greater leaf thickness than its zinc alloy equivalent — 5.6 mm versus 5 mm on the CL235-1, and 5.5 mm versus 4.8 mm on the CL235-2. This difference should be factored in when calculating door clearance or selecting screw length for stainless steel installations.

Application Scenarios

The Square Hinge with Countersunk Holes turns up on a lot of different cabinet types — distribution boxes, switchgear enclosures, control panels, and aluminum profile frame cabinets are all common fits. The square leaf sits flat and gives a solid bearing surface, which holds up well on doors that get opened and closed regularly or need to carry a bit of weight.

Where the Square Hinge with Countersunk Holes tends to get specified is anywhere the door face needs to stay clean and uncluttered. With screws sitting flush, there's no hardware standing proud of the surface to catch on wiring or snag during maintenance. The black zinc alloy version tends to go on dark or powder-coated cabinets; brushed stainless gets picked for outdoor enclosures or anywhere moisture is a factor.

FAQ

Q1: What are the two available sizes for this cabinet hinge?

The CL235-1 measures 64*79 mm and the CL235-2 measures 54*64 mm. Both are available in zinc alloy and brushed 304 stainless steel, with the zinc alloy versions also offered in black and bright white finishes.

Q2: What finish options are available?

The CL235-1 and CL235-2 cabinet hinges come in black zinc alloy, bright white zinc alloy, and brushed stainless steel. There is no mirror or painted stainless option in the current range.

Q3: Are screws included with the hinge?

Screws are not included. They are sold separately, typically in packs of 1,000 pieces or more. For smaller quantities, buyers can contact Yitai Lock directly to request pricing based on their required quantity.

Q4: How do I choose the right screw length?

Screw length should be selected based on your door panel thickness, the hinge leaf thickness, and how deep you want the screw to sit in the countersink. The countersink diameter on the CL235-1 is Φ8.5 mm for zinc alloy and Φ9.5 mm for stainless steel; on the CL235-2 it is Φ6.8 mm for both material types.

Q5: What is the difference in thickness between zinc alloy and stainless steel versions?

On the CL235-1, the zinc alloy leaf is 5 mm thick and the stainless steel leaf is 5.6 mm. On the CL235-2, zinc alloy is 4.8 mm and stainless steel is 5.5 mm. This thickness difference should be accounted for when selecting screw length and calculating door clearance.

Q6: Is this hinge suitable for outdoor enclosures?

The brushed 304 stainless steel version is appropriate for outdoor or high-humidity environments due to its corrosion resistance. Zinc alloy versions are better suited to indoor cabinet applications where exposure to moisture is limited.

Q7: What manufacturing process is used?

Both the zinc alloy and stainless steel versions of this cabinet hinge are produced by die casting, which ensures dimensional consistency and clean hole geometry across the production run.

Q8: Can this hinge be used on aluminum profile cabinet frames?

Yes. The square leaf design and countersunk hole layout make this cabinet hinge compatible with aluminum profile cabinet door assemblies, provided the mounting surface has sufficient thickness to accept the screw length being used.
